I have been discussing using SIPs with a few people in Northern Ontario, and they told me to look into them carefully since it seems that the ESA (electrical safety authority) or atleast some of there employees seem to think that SIPs cannot comply with electrical code. Does anyone know if there is any truth to this? I really want to use what seems to be a great technology, however the more things progress, the more SIPs seem to be prohibitive. Either it be costs, code compliance, and even some people involved within the industry (poor customer service from some individuals at some companies). It seems unfortunate that I am looking to be convinced into using what seems to be a good system. Do any others share similar thoughts ?

Also, are there people within Ontario, Canada that would be wiling to share positive experiences with SIPs? Did you use SIPs (either PWF or MgO) for foundation walls ? Thank you!

I am not familiar with the ESA, but imagine it is similar to the NEC. We don't use chases, we fur-out the walls and by doing so can be in full compliance with the code.

I agree with Chriss, the furring solution is the way it is done in Ontario and Quebec

As for an experience contractor in Northern Ontario for SIP'S foundation, here is a companie that has done some, call them and get info, ask then for references, you should be happy

Is this the case in the US? Most manufacturers offer the chases and some even charge extra to put them in. Seems odd that offered chases which appear to be the norm would be running afoul of inspectors. Any US builders that can comment. Having to furr out could very well tip the scale to a different system in some cases.

Hey bp f150, don't loose heart. I don't know a thing about Canada buildings, I live on the other side (Alabama gulf coat). When I first found out about sips it was like discovering homemade ice cream, I had to have it. Once you realize you are still on what is considered by most contractors as new and untested you can get a glimpse of why you will get some of the questions you will get.  Most contractors here in the south are 2nd and 3rd generation builders and they don't like change or a new guy telling them I found something better than you can give me. Inspectors that don't know about panels can't admit that to you or won't because of embarrassment so I was left with the burden of learning about building. I had no problem running my electrical through the panels in the chases provided. The electrical drawings on your plans do the work for you because the panel company puts the chases in place for you to run the wires through. Keep asking questions and I'm sure you will get the answers on this site.

Some additional benefits to furring out are:  better sound transmission rating, easy wiring access to fish wires for future receptacle or light fixture, adding with chases can involve major wall repairs

Human error !! is eliminated when furring out, I have done projects with chases and electricians will typically charge more because they liken it to a remodel job. It can be done, but I am all about making life simpler.
